Phantom static route

I have a ASA 5505 that was in a location that had power fluctuations. Its internal network is 192.168.252.0 another remote network thru a seperate t1 PPP link is 192.168.254.0. I had a route on the ASA as follows:
route inside 192.168.254.0 255.255.255.0 192.168.252.253 1
after the power fluctuations, the sh route states that its routing the 192.168.254.0 network to the outside. I tried to remove the router and add with no luck. Any ideas?
